Question
For this demonstration to the CEO, we're going to calculate the change in enthalpy, AH, for
the combustion of 4 compounds: methane (CH4), ethane (C2H6), propane (C3H8), and ethanol
(C2H5OH).
1) For each compound, complete the following steps:
a) Write a complete, balanced combustion equation using Lewis structures for all
species. An example for methane is shown below.
b) Make a list of all the bonds that are broken and formed during the reaction (see
also example below).
c) Calculate AH in kJ/mol using the equation above.
d) Calculate the AH in kJ/g.
